Atrial Septal Defect (ASD) is a common cardiac diagnosis among adults.Three-dimensional transesophageal echocardiography (3D-TEE) improve the visualization of ASD, its rims and surrounding structures and can be used for guidance during percutaneous transcatheter closure. Proper device size selection is important for success of ASD device closure. 3D-TEE can assess the ASD morphology, maximal diameter, area and determine the device size without balloon sizing during percutaneous closure.There are some adverse outcomes reported in previous studies following transcatheter secundum ASD closure as: residual shunt, new onset atrial fibrillation(AF) and mitral regurgitation(MR)deterioration . These adverse outcomes are responsible for morbidity and mortality following transcatheter ASD closure, so it is essential to study risk factors associated with these adverse outcomes in order to minimize their incidence.The investigators will study the role of 3D-TEE in proper device size selection, also the percentage and predictors of adverse outcomes after device closure guided by 3D-TEE.
